I've got a couple of the steel vacuum lines that are clogged. I'm planning on capping stuff up probably until I get something else to deal with it. What's the typical solution here? Just go all plastic? Is there steel still made in the same diameter?
I'd just take compressed air and blow the line out.
I agree with MIPS unless there's a rotted spot in the line it should come out with compressed air.
I have a line or two that won't blow out even with 90 PSI and I have another line that's cut. I think this had water in it/was disconnected for quite some time.
